Proposed standardized colour scheme for Robots

# Proposed standardized colour scheme for Robots:

E-Stop -> Red, Blinking
Auto Mode E-stop reset -> Yellow
Manual Mode E-stop reset -> White, Blinking

Manual Mode, No live handle depression -> White
Manual Mode, Live handle depressed -> Blue
Manual Mode, Program running -> Blue, Blinking

Mode Selection waiting for ack. -> Yellow, Blinking

Auto Mode, guard stop -> Red
Auto Mode, program stopped -> Yellow
Auto Mode, program running -> Green

Auto Mode, reduced speed -> Green, Blinking
Auto Mode, standstill -> Yellow, Blinking

## The following assumtions are made:

- Each start event while the robot is in automatic mode is proceded by a motors on even if nessesary.
- A blinking colour typically indicates that an action is required, or that spacial care is required.
- A safety reset event is a seperate command from a start event. The robot must go through red -> yellow -> green.

## How different people will interact with these colours

Operator/owner:
- Green means all is normal
- White means robot is not in use
- Yellow or Red means robot has stopped/there is an issue

Operator working collaboratively with the robot
- Same as normal operator, plus:
- Blinking green means robot is working slower due to detecting a person nearing the collaborative zone
- Blinking Yellow means the robot has stopped due to detecting a person in the collaborative zone
- Red means the safety system has tripped, for example when a person exceeded the collaborative zone

Washing/cleaning personnel:
- Red means robot is stopped and doors can be opened
- Any other colour means robot is in an unusual state and must be secured/stopped before entering the machine

Technician:
- White and Red means robot is safe
- Blue means the robot is being operated manually (pay attention)
- Green and Yellow means robot is dangerous

## note
In the case where a customer uses red to mean normal operation of machines, and green to mean safely stopped machines,
then green and red can be switched in the standard above.
